File-wrapper



UNITED STATES PATENT OFFICE.

ANNA C. GURSKE, OF OMAHA, NEBRASKA.

To all fr0/0m t may concern:

. Be it known that l, ANNaC. Grinsin, a citizen of the United lStates, residing at Omaha, in thecounty oi' Douglas and State of Nebraska, have invented certain new and useful Improvements in File-Wrappers, of which the following is a speciiication.

This invention relates to a ile wrapper of a type generally constructed of pasteboard, having a flat form and open at its ends, and arranged to be opened-and closed by bending its cover. v

The invention has for its object, broadly, to provide a file wrapper which will be convenient in `use and will consist `of few and simple parts so that it will be durable and may be economically manufactured. The

`invention includes resilient members atl cludes convenient means for connectingthe metallic, resilient members to the baclr ofthe wrapper. v f With the foregoing objects in view the invention presents a novel construction, combinationand. arrangement of parts, as. Ldescribedherein and claimed, and as illustrated in the accompanying drawing, wherein,-

Figure 1` is a topplan view olf the `tile wrapper, partly in section. Fig. 2 is a .bottom plan view of thesame.V Fig. 3 is a transverse section on line 3,.-3 oiFig. 1, the scale being enlarged. Fig. l is a similar view to that shown in Fig. 3, the cover-leaf being` released from the pressure-llap. Fig. 5 is a top plan view showing a pressure-flap and a part of the back. Fig. 6 is a bottom plan view showing a housing-strip and a part of the back.

Referring now to the drawing for a more particular description, the file wrapper consists, in part, of a flexible sheet preferably constructed of pasteboard, having a part bent, as indicated at 7 to provide a back 8 and a cover-leal' 9, and having a second part bent, as indicated at 10, to provide a pressure-flap 11 adapted to overhang a part of the back, said flap 11 being provided with a flange 12 adjacent to its longitudinal edge FILE-WRAPPER.

operative as a guide and useful as a liftingmember.

- In order that paper sheets or other contents 13 may be held, and will notslide outwardly of the open ends of the wrapper, and that the outer end portion of the leaf 9 may be held in closed position, l provide resilient members 1st, preferably constructed of pieces of wire, each being bent at its middle, as indicated at a to provide a pair of arms having portions b extending divergingly from the part a adapted to constantly engage the flap 11, and bent at its ends to provide a pair of loops or hooks 15` adapted to engage the back -8, s aid arms being bentto a ycurved form, as indicated at c, between said loops and divergent portions Z) to be disposed adjacent to the bent portion 10 of the flexible sheetf As thus described the parts of each member `1e` which are disposed upon the flap 11 are approximately-of V-shape and the degree oi' resiliency olf said members 14 is such that said il-shaped portions will be pressed against the flap 11 with considerable force so that the sheets or contents 13 will be securely held between said flap and the back 8.

lnorder that the loops 15 will be maintained in engagement with the baclr 8 I provide a housing-strip 16 and base-strip 17, each being traversed by the arms of the resilient members 14, the base-strip completely covering the loops 15, and the housing-strip covering the base-strip,siiitable adhesive material being used tory connecting the` housing-strip to the base-strip and for securii'ig` said members to the bach 8.

When the parts are disposed asshown in Fig. 3, the cover Sand sheets 13 will be securely held by the resiliency of members 14e. 'r

To open the lileviapper, the leal or cover 9 may be readily bent upwardly 'for removing it from beneath the llap 11, and when said leaf has been swung to open position, the flap 11, by action of members 1e will be pressed downwardly upon the sheets 13, and one or all of the sheets may be removed from the tile wrapper against the force of members lll, the flange 12 being used, when required, lfor manually lilting the flap 11. v

When placing the sheets 13 within the tile wrapper, they may have a sliding movement beneath the flap 11 toward the bent part 1U. Another function discharged by the flange 12, in addition to its use as a tab or liftingmember, is that it operates as a buffer for the projecting parts a, and prevents the latter from operating as obstructions to the movement of the paper sheets or cover 9 when inserting them beneath the flap 1l.

l/Vhile I have shown two resilient members let, it will be understood that the num-V ber thereof may be changed, and while I have shown and described construction in detail, I do not wish to be understood as limiting myself in this respect, and changes in size, form, proportion andl minor details may be made, as found to be of advantage, said changes to be determined by the scope of the invention as claimed.

I claim: l

l. A file wrapper, consisting ofV a flexible sheet having abent portion providing a back and acover and having a second bent portion providing a flap above the back, resilient, metallic strands for pressing the flap toward the back, each strand being bent'midway lbetween its ends to approximately V-shape to provide divergent parts adapted to lie upon the flap and providing curved parts adapted to be disposed adjacent to the second bent portion of the flexible sheet, and providing loops forengaging Y said back, a base-strip on the back disposed on saidV loops, and a housing strip engaging the back and base-strip, the flap of said flexible sheet being bent upwardly to provide a lifting-member.

2. In a file wrapper, the combination with a flexible sheet having a bent portion providing a back and a cover and having a second bent portion providing a flap above the back, of a resilient, metallic strand for pressing the flap toward the back, said strand being bent midwaybetween its ends to approximately V-shape to prov-ide parts adapted to lie upon the flap and providing curved parts adapted to be disposed adjacent to the second bent portion of the flexible strip, and providing loops `for engaging said back, a base strip on the back engaging said loops, and a housing strip engaging said back and base-strip.

3. In a file Wrapper, the combination with a rectangular, flexible sheet having a bent portion providing a back and a cover and having a second bent portion providing a flap above the back, of a pair of bent, resilient, metallic strands, each having a part disposed upon the flap for pressing it toward the` back and having a pair of loops engaging said back, and a housing-strip traversed by said strands, said housing-strip being disposed outwardly of the loops and ing the back, a housing-'strip secured to the back and traversed by the strands topermit the loops to be disposed between'the back and said housingstrip, the flap ofsaid flexible sheet being bent upwardly toprovide a terminal flange extending its entire length. l

5. A file wrapper, consisting of a rectangular, flexible sheet having a bentA p0rtion to provide a back and a cover and having a second bent portion providing a flap above the back, a plurality of resilient,me tallic strands for pressing the flap toward the back, each strand being bent midway between its ends to provide divergently dis-l posed partsadapted vto lieV upon the flap and providing loops for engaging the back, a housingestripsecured to the back and traversed by the strands and disposed"out wardly of said loops, the'fl'ap of saidffflexible sheet being bent transversely through'- out its entire length to provide aterminal flange. Y

In testimony whereof I have affixed my signature in presence of two witnesses.
